Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish locks for cases and drawers in museums and in other places, and for other uses where a number of doors or drawers are to be locked at the same time.

The invention consists in constructing a lock of series of sockets, series of bolts having sockets upon the sides of their bases, series of bearings, one or more sliding rods carrying the bolts, one or more bent levers, and one or more connecting-rods, whereby one or more series of bolts can be operated at the same time, as will be hereinafter fully described.

A represents a case, with a number of double doors, B, on each side. To the upper and lower parts ol' each door, or of one door of .each pair ot' doors, when double doors having interlocking or overlapping inner edges are used, are attached keepers orsockets G, to receive the bolts D. The bolts D have sockets formed upon the sidesof their rear ends to receive the rods E, to which they are secured by set-screws, rivets, or other suitable means. The inner sideslof the bolts D areslightly inclined or beveled, so that the said bolts will draw. the doors tight as the said bolts are forced into place.

Two sets of sockets, C, bolts D, and rodsE are used foreach set of doors, so that both ends of the said doors will be held firmly.

The rods E slide'in bearings F, attached to the case A, so that they will always move in the same line. Each rod E at one end is pivoted to anarmof an equal-armed bent lever, G, which is pivoted at its angle to and between a pair of lugs, H, formed upon plates (Model.)

attached to the case A. To the other arm of the bent lever G is pivoted the end of a verticalrod, I, the other end of which is pivoted to the arm of another bent lever, G, connected withanother rod, E, and set of bolts D.

When sets of doors upon two sides of a case are to be locked the pivot of one ot' the bent levers G upon one side of the case is connected with the pivot of a bent lever, G, upon the other sidev of the ease by a rod, J, so that the rods and bolt-s upon both sides of the case can be moved at the same time and by the same operation. The outer end of the pivot ot' one of the bent levers Gis squared and projectsinto an opening, K, in the side ot the case A, so that it can be turned to throw the bolts into and out of their sockets by means of a key, L, applied to the said pivot through the said opening K. The opening K also serves as a iiue to allow the airto escape as the doors are closed, which in the case of tight cases is very essential. The opening K is closed at the outer side of the case A by a plate, M, closing tightly to keep out dust, which plate is provided with a lock, N, to fasten it shut.

The supplementary lock N may be of simple or complicated construction, as desired.

With this construction a single rod, E, with its bearings F, bolts D, sockets O, and bent lever G, can be used, or one or more rods, E, and their attachments, as circumstances may require.

I am aware that it is not broadly new to work a series of bolts by one operating device.

Having thus described Vmy invention, what I claim as new, and desire to secure by Letters Patent, is-4 l. A lock constructed substantially as herein shown and described, consisting of the sockets G,the bolts D, made with sockets upon the side of their bases, the sliding rods E, the bearings F, the bent levers G, and the connecting-rods I and J, as set forth.

2. In a lock, the combination, with the series of sockets C, attached to a series of doors or drawers, ot' the series of bolts D, having sockets upon their sides, a sliding rod, E, a series of bearings, F, and a bent lever, G, having the end of its pivot squared to receive a IOO.
